I've gone ahead and implemented a few small fixes for Texture Manipulator 1.0.1:

• Switched the positions of the Image Display and the Button Panels so the buttons are on the left
• Enabled drag-and-drop functionality (Image files can now be dragged into the Image Display to load into Texture Manipulator)
• Fixed an error that could occur when using Iso-Left Rotation with images that are wider than they are tall

Please let me know if you guys run into any errors or strange behavior, and I'll do my best to fix it!
